Completly Glitched out

I downloaded this and didnt even make it through the first level and then it went to fullscreen and everything turned yellow and black and its all messed up. Ive deleted it, and reinstalled a couple times. But it still opens all yellow/black and glitches out, and i cant do anything. I continued to there website for support and the email couldnt be sent, because of there forum.
